Trump has scuttled the Iran deal, and made eventual war against that nation more likely.

At the same time, despite his cancellation of the summit with North Korea, already Donald Trump is changing his mind, and it now seems that the summit with Kim Jong Un might take place, but with unreasonable, irrational expectations.

To believe that North Korea will give up its nuclear program entirely is to believe in fantasy, as Kim Jong Un has now seen how unstable Donald Trump is. If Trump is ready to scuttle the nuclear deal with Iran and threaten them, what would make North Korea comfortable and confident enough that their regime would be left alone if they gave up their nuclear weapons?

Instead of saying can North Korea be trusted, how about whether the United States government under Donald Trump can be trusted to keep any agreement?

And in the meantime, Donald Trump has alienated our traditional allies in foreign policy, the NATO nations (and particularly Great Britain, France and Germany), and also South Korea and Japan, along with Canada, Australia and New Zealand.

Why should South Korea feel safe with an unstable, mercurial American leader who is fighting with their government over trade policy at a time when that nation could be decimated by a nuclear or conventional war with its neighbor?

One could say that American foreign policy in 2018 is the most unstable, unpredictable policy ever seen in American history since the end of World War II, and no sign of the return of any stability anytime in the near or long term future, as long as Donald Trump is President.
